Zucchini plants require 9 square feet around each plant.
you decide to use square tuvw to grow lettuce. you can plant four heads of lettuce per square foot. how many of each vegetable can you plant?

The area of square TUVW = 3×3 = 9 square units

1 square unit = 4 head lettuces
9 square units = 9×4 = 36 lettuces

Area of plot QRST = length × width = 12×6 = 72 square units

36 vegetables for every 9 square units
We have 72÷9 = 8 lots of 9 square units

Total vegetable = 8 × 36 = 288 vegetables

We can have 8 different vegetables, each type can have 36 vegetables
